Abstract

In this paper the effcts of simultaneous memory access on the fault modeling for two-port memories are investigated. New fault models and their march tests are presented. The obtained tests are of order O(n2), which makes them less practical for larger two-port memories. However, the complexity can be reduced to O(n), when the memory topology is taken into account.
